I wasn’t sure how this soup was going to turn out in the slow cooker, but I went ahead with the idea and, since I am sharing it here, you know it was a really good call. A delicious one, at that. Really, though, I only made a couple of adjustments. Traditionally, french onion soup is made with beef stock. I used chicken stock instead. Also, I didn’t cook the onions for forever and a day; 20 minutes was enough. Wish I could find a way around slicing them – my eyes are still burning. But, this is one of my favorite soups, so a bucket of tears is always worth it. If time permits, and the baby takes a longer nap, I think I’m gonna go make this happen again today. Maybe I will ward off some germs and viruses… ENJOY!

Katerina Petrovska says
Hi Kate!
You can use apple juice and a tablespoon of lemon juice. I hope that helps! Have a great day!
Kristin says
Anyone tried freezing this soup?
Katerina Petrovska says
No, I’ve never tried freezing it. I know it stays good in the fridge for a couple of days.
Audra says
Just an idea…I am making the soup as I type! I used a vegetable slicer for the onions, no tears! Also another tip is breath through your mouth not your nose, it works! 🙂 thanks for the yummy recipe!
Katerina Petrovska says
Thanks SO much, Audra, for sharing those tips! Believe me when I say that I will be using them asap – I hate the whole onions/crying thing. 😀
Hope you enjoy the soup!!

We need some of this soup and Sandra’s onion tea (I’ve heard of that before) for my kiddos too. This is one of my favorite soups. Yours looks fantastic!

Hope your little one feels better soon! I had a sick household yesterday {hubby & both kids}, so I made them a big batch of tomato soup. French Onion is one of my favorites & this looks divine!!
Sandra's Easy Cooking says
Yup your granny is right , onions are full of vitamins C and I make tea for my kids when they are sick with onion..I know sounds disgusting but with some honey and lemon you could never tell it is with onions(w/peel). I hope your kiddos feel better soon! :*
Your onion Soup looks fantastic, loving your presentation and recipe is tasty too!
Jen @ Savory Simple says
I just love the idea of making this in the slow cooker! One of my favorite soups.
Kristy says
I hope the little one is feeling better and that it’s not spreading around the house. 🙁 Today is a day of coincidences I think. I’m catching up on blog reading tonight and the last post I read was also for French onion soup – which I’ve never had. And even more coincidental, I saw it on a menu this morning and decided I need to try it. I’m loving this slow cooker version – my kind of meal! 🙂
Dan says
This is a great idea that I’ve got to try. My brother once showed up with a scuba mask to chop onions. It seemed to work well for him.
Kate@Diethood says
That is hilarious! Lol!
Terra says

Parsley Sage says
Oh! I hope your lumpy feels better soon 🙁 That’s always a terrible thing to have to see.
Do love this soup though! Winter is fast approaching in Cayman with temps dropping into GASP the 70s! Believe it or not, that totally calls for slow cookers. Bookmarking this bad boy!

I love you made this in a slow cooker! Yum. I could seriously eat an entire pot of this soup alone…
Ramona says
I think I love your idea of changing the beef broth to chicken. I prefer chicken flavor and I will definitely give this recipe and cooking method a try. Onions are very healthy…. and I love them. 🙂
I hope your sweet baby gets well quickly… I know it’s emotionally and physically tolling for parents when they are sick. My kids have coughs now and I wish I could magically get them better.
Have a good weekend. ~ Ramona

My husband and I looooooooooooove French onion soup and we order it when it’s available. We’ve made once at home but it’s been a while. I don’t own a slow cooker but maybe I can cook slowly on a cast iron? Looks so delicious!
